IMPROVEMENT IN-HVDRANTS.

Spec-cation forming part of Letters Patent No. 164,489, dated J une 15, 1875 application filed March 29, 1875.

To all whom it may conce/rn:

Be it known that I, WALTER SCOTT, of Passaic, in the county of Passaic and State of New J ersey, have invented a new and Improved Hydrant, of which the following is a specification t The invention will first be described in connection with drawing, and then pointed out in the claim.

Figure l is a sectional elevation of my improved hydrant. Fig. 2 is a horizontal section of Fig. l on the line x rv,- and Fig. 3 is a horizontal section on line y y.

Similar letters of reference indicate corresponding parts.

A is the stand-pipe, B the branch connecting it with the main, and D the horizontal discharge-pipe at the top.' E represents the plug-valve, which I propose to use arranged in the branch B, outside ot the stand-pipe, with its stem F arranged in a hole, G, through the pipe O for its upper bearing. This arrangement enables lne to utilize the extra passage H of a three-way cock for opening an escape-passage, I, which I also provide in the shell of the cock for opening when the main passage is closed, to let the water escape from the stand pipe. Thus `I get awaste water passage for a hydrant, and means for opening and closing it much simpler and more reliable than has yet been contrived. In connection with this arrangement I extend the curb J down below the valve, to protect it from dirt, &c.; and to carry the Waste Water outside of it, I attach the pipe K in connection with the passage I.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with branch B and escape I, ot' three-Way cock E, provided with stem F, having its upper bearing in pipe O, as and for the purpose specified.

WALTER SCOTT.
